Razorgage ST-A Automatic Saw Measuring System


The RazorGage ST-A Automatic Saw Measuring System is an automated, programmable saw stop with a hi-resolution touchscreen Android interface that enables fast, easy and intuitive operation — no matter your settings and desired part lengths. Fraction keys eliminate the need to memorize decimal equivalents or make calculations on the fly — the RazorGage ST-A does the math for you!

The ST-A digital saw stop and pusher is built using all of the same CNC quality mechanical features used in all our ST configuration positioners, but without the full functionality of the RazorGage Windows application software.

When looking to improve the output and efficiency for your operations, the RazorGage ST-A Automatic Saw Measuring System offers the highest degree of accuracy, repeatability and long-lasting dependability.

Product Info

The saw stop and pusher capabilities for the ST-A are controlled with a streamlined user-friendly Android tablet interface. With “absolute” mode, the operator can use the RazorGage ST-A as a saw stop, loading materials and achieving precise measurements. In “incremental” mode, the ST-A becomes a pusher, moving material forward and making multiple cuts according to custom increments. 

The Android tablet can store thousands of cut lists, and it has simple, intuitive menu screens and options. Just like the RazorGage ST, the ST-A programmable saw stop features a high-performance motion controller that reacts quickly to jambs, eliminating stretched belts. The RazorGage ST-A comes with a 5-year belt warranty just like the RazorGage ST.

The carriage assembly features a Hiwin hardened and ground linear bearing rail with two recirculating ball bearing blocks — just like you see on CNC machine tools and machining centers. This enables nearly friction-free motion, maximum rigidity, accuracy and long life. The RazorGage ST-A can be used for automatic miter saw measuring, or it may be installed for use alongside other types of saws.

RazorGage ST-A Digital Saw Stop Software

The Android’s large hi-resolution touchscreen makes operator input fast, easy and intuitive.  Fraction keys, unlimited hotKeys, and the cutlist screen with kit quantity multiplication and cutlist sorting features make this entry-level interface a powerful ally in the fight to improve quality and productivity.

You can create your cutlists right at the machine or send a cutlist over a WiFi network. The Android tablet has tremendous storage capacity, so you will be able to store many cut lists, big and small. Furthermore, the cut lists can be restored to original quantities after use or even multiplied should you want to make several “kits” of parts at once.

If you’re investing in an automatic saw measuring system, you want a product that is dependable every single day. Replacing parts and paying for repairs will cut into your ROI. To get the most out of your new programmable saw positioner, choose one with superior components made of high-quality materials.

For example, the positioning carriage on a RazorGage automatic saw system is mounted on recirculating ball bearing blocks rolling on hardened steel. Competitors use plastic and aluminum — materials that are much more prone to inaccuracy and wear. RazorGage components are designed to minimize backlash, reduce wear and ensure a high level of accuracy and consistent performance time after time. By comparison, our competitors’ components are lower quality, and it shows in the overall poorer performance of the positioner.

1. RazorGage: Positioning carriage mounts on two re-circulating ball bearing blocks sliding on a hardened & ground steel rail. Just like you see on CNC machining centers!1. Competitor: Uses plastic strips sliding on aluminum as the positioning carriage bearing.
2. RazorGage: Electronics are sealed inside IP54 rated housing impervious to chips.2. Competitor: Electronics sensitive to chips are inadequately protected.
3. RazorGage: Utilizes a planetary gear-head with 3 load paths transmitting torque & less than 7 arc minutes of backlash to maximize accuracy.3. Competitor: Spur gear style reducer others use, with 1.2 gear teeth transmitting load, is prone to excessive backlash.
4. RazorGage: Uses no sensors for homing or end of travel eliminating the need for failure prone components and wiring.4. Competitor: Contamination sensitive sensors inside the beam require long cable runs around sharp corners.
5. RazorGage: 30 tooth drive pulley used on RazorGage has a larger bend radius increases belt life and twice the teeth to resist tooth shear.5. Competitor: 15 tooth pulley competitor uses, has a tighter bend radius reducing belt life and half the teeth to resist tooth shear.
6. RazorGage: The RazorGage drive pulley is machined to match the belt tooth profile eliminating backlash.6. Competitor: Standard pulleys have 1/64” clearance allowing backlash which reduces accuracy.
